I believe it'll mainly be about if and when those images were registered with the U.S. Copyright Office. The slightly mean but correct play in those cases is to: 1. Register your images with the USCO 2. Send them a friendly email that you'd appreciate if they would license your images in general, without explicit examples. 3. Wait for the next update/patch/release that distributes your images. 4. Now you're suing for willful infringement including statutory damages.
